UNITED STATES PATENT OFFICE.

G. M. lVOOD, OF DECATUR, ILLINOIS.

IMPROVED KEEPER FOR BOLTS.

Specification forming part of Letters Patent No. 58,929, dated October1li, 186V.

To all whom it may concern:

Be it known that I, G. M. WOOD, of Decatur, in the county of Macon andState of lllinos, have invented a new and useful Improvelnent in Keepersfor Bolts; and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable others skilled in theart to make and use the saine, reference being had tothe accompanyingdrawing, forming part of this spccitication.

The drawing represents a front or face view of myinvention.

The object of this invention is to obvate the difficulty attending thesagging ot' doors, shutters, &e., to which bolts are attached. Then abolt is first applied to a new door and the keeper secured in line withit on the door-frame, the keeper will, of course, receive the bolt; butall new wood .will eventually shrink more or less, and the door sag in agreater or less degree, and frequently to such an extent that the boltcannot enter the keeper.

My invention consists in having the keeper formed with oblong slots forthe screws which secure the keeper in position to pass through, andwhich admit of the keeper being adjusted to compensate for shrinkage andthe sagging ot the door.

In the accompanying drawing, A represents the keeper of an ordinaryslide-bolt. Slidebolts are not generally alfeeted by shrinkage of thewood, as they have a considerable length of movement to admit ot thementering the keeper, even it' the door and doorfralne should shrink verymaterially; but they are very frequently rendered useless or inoperativeby the sagging ot' the door, and heneel construct keepers for thispurpose with vertical slots a a for the screws b to pass through, tosecure it to thedoor-frnnie. These vertical oblong slots admit ofthekeeper heilig adj usted downward in ease the door to which the bolt isattached sags, and hence the keeper may always be kept in line with thebolt.

The adjustment ot' the keeper, in event 0f the contingencies specified,is shown in red.

Having thus described my invention, l claim as new and desire to secureby Letters Patent- The providing of the keepers of bolts with oblongscrew-slots, in the manner substantially as and for the purpose sett'orth.

The above specification ot' niy invention signed by me this 2lth day et'April, 1866.
